ABSTRACT:
A boom and mast apparatus includes a transverse support member which has a proximal portion and a distal portion. A longitudinal mast assembly is connected to the distal portion of the transverse support member. The longitudinal mast assembly includes a support-member-connected end and a boom-member-connected end. The longitudinal mast assembly also includes a lower segment connected to the transverse support member, an upper segment, and a connector assembly for selectively connecting the upper segment to the lower segment. A first bearing ring is connected transversely to a topmost portion of the lower segment. A second bearing ring is connected transversely to a bottommost portion of the upper segment. The second bearing ring is placed in registration with the first bearing ring when the boom and mast apparatus is assembled. A boom member is connected to the boom-member-connected end of the longitudinal mast assembly. A winch assembly is connected to the upper segment of the longitudinal mast assembly. A winding strap is wound by the winch assembly. A bottom portion of the lower segment of the longitudinal mast assembly is hollow and receives a support leg assembly which can selectively be retracted into or extended out from the bottom portion of the lower segment. The support leg assembly includes a leg member and a base member. The leg member includes a plurality of adjustment channels.
